We have a C# application that uses the PDF converter printer. Our application first generates a formatted HTML file, and then converts it to PDF using the BatchConvert method. 99% of the time this works fine, but recently we had several customers complain about fonts in the PDF output. All of them are using Windows 7. I analyzed a couple of PDF documents using PDF Analyzer. When I look at a properly generated document, the Fonts listed by the analyzer are Verdana, Verdana Bold, and Times New Roman, which is as expected. When looking at an affected document, the Fonts seem to be scrambled up - the font names are listed as "94eqfti Bold", "60pupek", and "57ypccyjeddqqna". The HTML file used as source seems fine; only the PDF is affected. When viewed in Adobe, most of the data is displayed using what seem to be default fonts, but some of the content is missing, and I assume it is because of these strange fonts.
Has anybody run into anything similar, or has any ideas on what could be causing this?
Thank you very much.
